CARBOY LIFT.

Application filed May 4,

To all whom it may concern:

Be it known that Ro'scon B. SHIFFNER, a citizen of the United States of America, residing at Kansas City, in the county of Jackcs son and State of Missouri, has invented new and useful Improvements in Carboy Lifts, of which the following is a specification.

The object of the invention is "to provide a relatively simpleand elficient means Where- 10 by carboys and like containers ordinarily employed for the storage and transportation of acids used in various arts and manufactures may be lifted, moved and tilted to discharge their contents under conditions con- 1 venient to the operator without involving any considerable effort and without subjecting the operator to the risk of spilling or wasting the contents of the receptacle or of becoming splashed thereby; and more par- 20 ticularly without involving the risk of breaking the container which usually is made of glass as a material best adapted to resist the action of the contents; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompany drawings, wherein Figure 1 is a side view of a carboy lift and cradle constructed in accordance with the in vention, a carboy being shown seated thereon.

Figure 2 is a rear view of the same.

Figure 3 is a side view in carboy receiving position.

The apparatus embodies essentially a platform or seat for the carboy which is shown at 11 and is carried by parallel rockers 12 connected by transverse strips 13 forming said seat and strips 1 1 forming a back, said seat and back being arranged in perpendicular relation to receive the carboy, handles 15 being arranged on opposite sides of the seat in a plane about midway of the depth of the seat and being braced near its upper end by a bar 16 connected with one of the rockers, a further diagonal brace 17 being arranged upon each rocker in intersecting relation with the angle between the seat and the back to strengthen the structure.

The rockers are preferably shod at their bearing edges as indicated at 18 with strap iron or the equivalent thereof, when as may be preferred the body portions of the rockers are constructed of wood, as a means of increasing the durability thereof and the facility with which the carboy can be bodily 1921. Serial No. 466,646.

gloved over a supp'orting surface such as the Moreover the rockers may as shown be provided at their normal lower ends, in parallelism with the seat 10 with a flat bearing "surface 19 upon which the structure may be supported as the carboy is being placed thereon, the latter being tilted away from the cradle so as to incline the bottom thereof sufficiently to be arranged on the front edge of the seat, after which the carboy can be slid forward until it comes into contact with the back represented by the transverse strips 14. A retainer of flexible material such as chain is indicated at 20, the same consisting of members attached at their lower ends as at 21 to the portions of the rockers beneath the seat and thence being extended upward substantially paralled with the handle 15 and interlocked at their upper ends above the top of the carboy by means of a hook and eye or equivalent fastener as indicated at 22. This retainer serves to prevent the movement of the carboy in a direction parallel with the back when tilted to the discharging or emptying position indicated in dotted lines in Figure 1. The seat provided for the reception of the carboy is preferably provided with metallic runners 10 consisting of metallic strips serving to facilitate the sliding movement of the carboy in positioning the same on the cradle.

The portions of the bearing edges of the rockers between the points a and c are'curved and may as shown be struck from a common center which in the construction illustrated is indicated at d at or about a vertical plane of the centers of the carboyand above the plane of the center of the height or middepth of the carboy, such mid-depth being indicated by the dotted line 6, so that the height of the rocker from f to the line 6 representing the mid-depth of the carboy is about in the proportion of three to four to the portion of the height of the rocker between the line 6 and the point 0.

The curve of the bearing edges of the rockers having its center slightly above the mid-depth of the carboy and hence slightly above the center gravity of the carboy and its contents, the tendency of the cradle is direction therefrom, and the curve of which this bearing point constitutes the approximate center is that of which the brace 17 represents the chord, so that the seat and back provided for the reception of the carboy, in the normal or neutral position of the cradle diverge upwardly on planes substantially at equal angles from the plane or" the horizon.

A further consequence of the arrangement and relative disposition of the parts indicated is that in tilting the cradle forward to discharge more or less of the contents of the carboy into a receptacle provided for the purpose a downward pressure upon the handle 15 is necessary throughout the operaticn and regardless of the extent to which the contents of the carboy have been dis charged, so that upon release of the handle or removal of pressure therefrom the cradle immediately swings back to the neutral position and thus assumes a condition of stable equilibrium with the carboy in position to prevent discharge of the contents, whether the top of the carboy is plugged or sealed or not, the usual stopper 2a being provided for preventing evaporation of the contents. Notwithstanding the stable construction of the device, however, it will be obvious that it may be tilted in one direction on the other, to either permit of the placing or displacing of a carboy with relation to the seat or to pour the contents of the carboy from the unstoppered neck, with a comparatively slight efiort on the part of the operator.

To support the cradle in a position to permit of the seating of a carboy it is preferably provided with standards or legs 25 pivoted as at 26 to the rockers and adapted either to be extended as shown in full lines secting relation with the angle between the seat and the back, handles secured to the rockers on opposite sides of the seat in a plane midway thedepth of the seat, brace bars disposed in parallelism with the seat and connecting the handles with the rockers adjacent the upper ends of the former, legs pivotally connected with the rockers and adapted to maintain the device in upright position when the seat is disposed in a horizontal plane, and a flexible retainer consisting of detachably connected chains having their extremities secured respectively to the two rockers and adapted for spanning relation with a carboy carried on said seat.

In testimony whereof he aflixes his signature.
